Here are our Top 5 gravity-flipping games on Android.

One of the most popular gravity-flipping games out there, Gravity Guy is a no-nonsense endless-runner with a gravity-flipping twist. It still feels fresh, thanks largely to a brilliant same-handset multiplayer mode for up to four players.

We've been eagerly waiting for this indie gem to make its way to Android for what feels like ages. VVVVVV is a fiendish retro platform-puzzler that sees you working your way through a labyrinthine world by flipping from floor to ceiling.

Here's a clever little game that uses gravity manipulation as its main puzzle-solving mechanism. Guide Zuki through a bunch of booby-trapped temples by swiping the screen to shift gravity in one of four directions.

Flip Runner presents the whole gravity-flipping endless-runner thing a little differently. Here, you're running along a single central platform. And when you jump, you disappear off the top of the screen and re-appear upside down on the other side of the platform. As if the whole gravity-flipping concept wasn't sufficiently brain-frying...

The purpose of switching between the floor and the ceiling in Gentlemen isn't simple evasion or puzzle solving - it's to facilitate taking out your mortal enemy in one-on-one combat. A rare same-handset multiplayer combat game, and one that has gravity-flipping at its core.
